Title: Mold for semiconductor package
Inventor: MATSUMURA YOSHIHIRO
IPC: H01L21/56
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To reduce defects such as voids and drawbacks by a method wherein a linking path which links a cavity corner part on a gate side with a cavity horizontal plane is provided. SOLUTION: A mold for a semiconductor package comprises an upper mold 11 and a lower mold 12 which are coupled with coupling surfaces. Trenches are formed as a gate 1 and an air vent 2 in the coupling surface of the lower mold 12. In the mold for a semiconductor package, a linking path 8 which links a cavity corner part on the gate 1 side with a cavity horizontal plane is provided in the cavity horizontal plane on the side which faces a semiconductor chip 5, i.e., in the upper mold 11. Even if the air staying in the mold for a semiconductor package is increased, a pressure at the cavity corner part is approximately equal to the pressure at the cavity horizontal plane. With this constitution, a semiconductor package which has few void defects in the gate side corner part can be molded without the precise control of molding conditions.

Title: Snow gun
Inventor: MIKAERU MANHARUTO
IPC: B05B7/04
Filed: 1983-01-18
Abstract: The compressed-air supply line of the snow gun passes through the center of the pressurized-water supply line, thus bounding an annular chamber between them. Inner nozzles forming part of the air line interconnect the two supply lines. The compressed-air supply line opens out into an interior space within the spray head, this space being bounded at the front end by a perforated end piece. For the purpose of reducing the expenditure of energy for a given homogeneity of the air-water mixture, the radial width of the annular chamber in the vicinity of the inner nozzles is from one to three times greater than the diameter of an imaginary bore whose area corresponds to the total area of all inner nozzle bores, divided by three.

Abstract: PURPOSE:To make impossible the forgery of an IC card, to prevent an improper use even when it is stolen, and to improve security by collating a password number specified for its owner at an IC card side, and checking it at a reader/ writer side only when they coincide. CONSTITUTION:When the collating process operation of an IC card 1 is started, the presenter of the card 1, first of all, inputs the password number to the reader/writer.

As a result, it is decided that the presenter of the card 1 is its owner only when they coincide, and a result is outputted after a prescribed arithmetic process is applied on the password number. And at the reader/writer side, the collating between the password number sent from the IC card and the password number inputted by a card presenter is performed, and when coincidence between them is obtained, the information to permit the usage of the card is outputted. In this way, the forgery of the card is impossible, and the improper use of the card can be prevented even when it is stolen, thereby the security is improved.

Abstract: PURPOSE:To transport sheet members one by one without being damaged, by making the outer peripheral surface of a transport roller from the material having the larger frictional coefficient for the sheet material and making the outer peripheral surface of a separating roller from the material having the smaller frictional coefficient for the sheet member. CONSTITUTION:A transport roller 1 and a separating roller 2 are opposed so that the axis lines are set parallel and a small gap is kept between the both outer peripheral surfaces.
